If no separate power lead set to the floppy drive, the pinout would be proprietary. Some leads of the ribbon supply power to the drive! Floppy drives went out of favor about 10 years ago.. capacity, reliability problems.Maybe some help here.. http://www.datasheetarchive.com/FLOPPY% ... sheet.html

Thanks for your answer, evasive: I already checked most of the link you posted except for the Vogons one, will test it in the following hours.

In the meantime here's the pictures you asked, the BIOS screen must be the funkiest one I've seen regarding its colorscheme. I'm kinda digging it since it seems full of options (more than I can remember on my other 486 computers).

The BIOS code (it reads: 30-0500-ZZ1453-00101111-070791-ACER1217-H), do you find something interesting reagrding it apart from its date? > EDIT: OK I deciphered it with a table I found on the web: it seems that's a 386CPU BIOS whereas the CPU marking of Texas Instrument shows a 486SL. Maybe the TI CPU is a pimped up 386?http://imgur.com/fNwgyDW

An adjustment has been made to your account so you should be able to now post freely.

The moderation situation is necessary due to the unwillingness to properly maintain the forum software by the owners of the site leading to a spam fest if the moderation limit is not in effect..

That BIOS code you noted, [30-0500-ZZ1453-00101111-070791-ACER1217-H], shows a conception date of July 07 1991. Then the "Acer" brand.Not unusual to see those 'funky' colors with older BIOS images. Just a bit of 'bling'. Some had a choice of color schemes. Most of the older BIOS versions (early 486 and older) did not have an auto-detect for the hard drive, so manual choice of what was listed, or 'user-input' was mandatory. If the hard drive specs were not within the BIOS limits, you might be able to fool the BIOS check by doing a 4x head count and 1/4 cylinder count. But the SPT (sectors per track) cannot be changed. There also may be a choice of 'standard' or "LBA" (logical block addressing) for specs.

I gave you the pinout of the FDD and more than one conversion table to 34 pins. I suspect there's more projects out there to connect a 34pin floppy to a 26pin controller, just take your pick on which one seems feasable to build yourself.

We hate rut, but we fear change.

Yes I saw, sorry my post was written as if I would try a random pinout. I'll try the pinout you provided via the VOGONS link and let you know! Cheers!
